Dropbox Uploader App in UI7 VeraEdge

New Vera user (VeraEdge). I have added the Dropbox Uploader app and it does upload images successfully to a dropbox account. However, when I go to devices, click on setting for the device, it give me the opportunity to change the upload frequency in minutes and also days to retain the images. However, there is no SAVE button, only a “back” hyperlink. My question is how do I save my changed settings in UI7?
